STUMP AND TREE FULLER.

Specification of Letters Patent.

Application filed March 26, 1908. Serial No. 423,351.

Patented June 2, 1908.

To all whom it may concern:

Be it known that I, STEPHEN 'MATHIAS SMITH, citizen of the UnitedStates, residing at Boise, in the county of Ada and State of Idaho, haveinvented certain new and useful Improvements in Stump and Tree Pullers,of which the following is a specification.

My invention relates to an improved apparatus for the pulling of treesor stumps of trees from the ground, and it has for its object theproduction of an apparatus for this purpose which is simple in characterbut which will greatly magnify the power' applied thereto and be capableof pulling out from the ground trees and stumps oflarge size and whichare firmly rooted therein, and this without necessity of previouslyexcavating the earth from around roots of such trees or stumps or ofcutting the roots thereof.

A further object of' my invention is the production of an apparatus ofthis character in which there is employed a minimum of parts, therebyreducing the weight of the apparatus in transporting the same from placeto place and where the-same is employed in a new or thickly-woodedcountry it is usually dragged from place to place by the team employedas the power applied thereto. The few parts employed also results in thereduction of friction in the operation of the apparatus as well, as aresultant economy in the production of such parts.

With these and further objects in view my invention consists in certainconstructions, combinations and arrangements of parts the preferred formof which will be first described in connection with the accompanyingdrawings and then the invention particularly pointed out in the appendedclaims.

Referring to the accompanying drawings wherein the same part isdesignated by the same reference numeral wherever it occurs, Figure 1 isa perspective view showing the apparatus as applied to a tree andindicating the several parts thereof in the relative position foroperation to pull down the tree; Fig. 2 is a perspective view showinghow the apparatus is preferably attached to a stump to extract the same;and Fig. 3 is a detail view showing the preferred form of knot used toattach certain of the blocks to the running part of the cable.

1 designates the tree or stump to be pulled down or extracted.

2 designates a tree or stump which forms the anchorage.

3 designates a line or cable provided on one end with a hook 4 and onits opposite end with an eye 5. This cable is adapted to be passedaround the tree or stump to be pulled and the hook engaged over thecable as shown. The hook is secured to the cable in such relation to theanchorage that the pull comes on the side of the tree instead ofdirectly in front, in order to give the tree a twist, in addition to thepull, thus materially assisting in loosening the same from the ground. 7

Around the stump or tree 2 which forms the anchorage, I pass a cable 6provided with a hook 7 at one end, and an eye 8 at the other, whichaffords a ready means of attaching a standing block 9, secured to theeye 8, to the anchorage by merely passing the cable 6 around theanchorage hooking the hook 7 over the cable.

10 is a single block attached to the eye 5 of the cable 3 in any desiredmanner. Through the blocks 9 and 10 I reeve a cable having a fall 11provided with an eye 12 in its end. The running portion of the cableextending between the blocks 9 and 10 I designate as 13.

14 is a block secured to .the eye 12, and the cable, after passingaround the sheave of the block 9, extends over the sheave of the block14. The portion of the cable between the blocks 9 and 14 I havedesignated as 15. Bent on the cable 15 preferably by means of the doublehalf hitch bend shown in detail in Fig. 3, I secure the block 16, thisblock being bent on the cable near the block 9. The cable after passingthrough the block 14 passes over the sheave of the block 16, the portionof the cable between the blocks 14 and 16 being designated 17. Bent onto the portion 1.7 of the cable is a block 18, the

block being preferably secured by the hitch the pulley 14 upon therunning end 11 will likewise be double the power of the section 17, andsimilarly the power exerted by the running block 10 will be double thattransmitted by the block 14. In addition ,to this multiplication ofpower, it will be noted that there is exerted by the section .19 of thecable a pull upon the section 15, which is double the power exerted uponthe fall 20 and, consequently, there is transmitted through the ulley 9a similar amount of power which further increases the power delivered bythe block 10.

While I have described my apparatus as comprising five blocks, it is tobe noted that the number of blocks can be increased which will cause thepower delivered to the standing block to be correspondingly multiplied.The form of apparatus disclosed in this application is, however,sufiicient to enable a pair of horses to pull over trees and uprootstumps of any ordinary size.

While I have described my apparatus as being particularly adapted forpulling stumps and trees, it is equally applicable for use wherever alarge multiplication of power is required.

In Fig. 3 I have shown my preferred form of arrangement for pullingstumps, in which I place under the cable 3 a log 22 which will give thenecessary pull and twist to uproot stumps.

I realize that considerable variation is possible in the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and I therefore do not intend to limit myself to thespecific form shown and described.

I claim In an apparatus of the character described, the combination witha running block, of a standing block, a cable reeved through saidblocks, a third block connected to the running end of the cable adjacentto the running block, the cable extending from said standing blockthrough said third block, a fourth block bent upon the cable between thesecond and third blocks, said cable extending from the third block andreeved through the fourth block, a fifth block bent upon the cablebetween the third and fourth blocks and the cable reeved through saidfifth block.

In testimony whereof I affix my signature in presence of two witnesses.

STEPHEN MATHIAS SMITH.
